To all whom it may concern:

Be it known that 1, JOHN E. SPRINGER, a citizen of the United States, and resident of Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Alloys, of which the following is a specification.

My invention relates to improvements in alloys or compounds, and it consists substantially in the ingredients and proportions thereof, as herein specified and claimed.

One of the foremost objects sought to be accomplished by this particular compound, is to produce a metallic alloy possessing the important advantages of lightness, strength, ductility and relative cheapness.

following ingredients Furnace slag Humite 8% Copper 20% Nickel 5% Zinc 5% Tungsten 5 Iron 2% Manganese 5% In making a batch or quantity of the al loy, all of the above ingredients are taken at once and placed in a furnace, being there heated to a melting temperature. nace slag and humite act as fluxes which aid the commingling :ot the metallic elements in producing the final alloy. The molten mass is poured into a flask or mold. After the article has cooled it is heat treated or annealed, which treatment, as is commonly known, consists merely in bringing the article to a predetermined temperature and then again permitting it to cool.

The above schedule gives the proportions of the ingredients in percentages. From The alloy The furall ingredients together aturc molding the resultant alloy, andan- Specification of Letters Patent. Pat-rented A111. 25, 1922. Application filed August '13, 1920. Serial No. 403,268. i I

this it is an easy matter to compute the relative weights of the various ingredients for any desired total weight of alloy. the ingredients are familiar buthumite may be identified as a mineral oi the chondrodite variety, crystalline and translucent, brownish-yellow to white in color, composed of magnesia, silicia, fluorine, and protoxide of iron. i g

The alloy is rust-proof, non-corrosive and does not deteriorate. The uses to which it can be put are many, stated; it may be made into telegraph poles, rail road ties, lintels, roofing plates, paving blocks, sheet piling, plates are made, the material is cast in sheets approximating the ordinary slate shingles. Since the alloy ductility, such plates'inay be readily shaped to any form desired A special application of the alloy is that to making railroad ties,

in which case the ties are made hollow.

I claim:

1. The herein described lnethod of making an alloy consisting ot taking the following inetailic ingredients and proportions thereof; copper 20%, nickel, 5%, zinc 5%, tung ston 5%, iron 2%, manganese 5% and the fluxes furnace slag 50%", humite 8%; heating to a melting temper healing it. k 2-. The herein described allow comprising the followir n redients and proportions .t 6 thereof remaining after meltingwith the fluxes furnace slag 50% and humite 8%. copper 20%, nickel 5%,Zi110 5%, tungsten 5%, iron 2%, manganese 5%. 1
